PIN.

Specification of Letters Patent.

' "atented Nov. it iitiiil.

Application filed November 4, 1911. Serial No. 658,505.

To (4Z6 whom '1' t may concern Be it known that I, CHARLES F. \{ARK- nan, a citizen of the Unitet States, residing at the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful improvements in Pins, of which the following is a specification, reference being had there-- in to the accompanying drawing.

This invention relates to pins of the class commonly known as beauty or cuff pins, and has for its object to provide a so-callcd one piece pin, the same having its joint and its catch member formed integral. with the body portion thereof and yet of thicker or heavier stock than that of which the body portion is formed so that a pin formed of precious metal need not all be of heavy stock in order to obtain the necessary strength at the points where strength is required.

The invention further consists in forming a tongue integral with the end of the body portion the same being slotted and bent over toward the opposite end of the pin and back upon itself with its end extending into the hollow body of the pin and resting against the bottom of the pin body a loop being formed in the bend for the reception of a 'l head pin stem.

The invention still further consists in providing lateral extensions near the end of this member so that when the same is drawn over into position to form the joint member, the edges of the pin body may be rolled over these laterally extending portions on either side to lock the same firmly in position within the pin body.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed and particularly pointed out in the appended claims.

0f the accompanying drawings: Figure 1 is a side elevation showing a pin having a joint and a catch member of my improved construction. Fig. 2 is a plan view of my improved pin. Fig. 3 is a plan view illustrating the general shape of the blank having extending portions at either end from which the joint and catch members are formed respectively. Fig. 4 is a side elevation illustrating the extending end portions, and the main body portion as having been reduced in thickness or made thinner than that of said end portions. Fig. 5 is an enlarged side elevation partly in section illustrating the general construction of my improved joint member. Fig. (i is an end view sectioned on line 6-6 of Fig. 5 looking in the direction of the arrow and illustrating the edge of the body rolled over that of the lateral extension for locking the end of the joint member into the pin body.

My present invention relates more partic ularly to a so-called one-piece pin and in the drawings of which I, designates the body thereof, 2 the joint member, and 3 the catch member, both of which latter are formed integral with said body portion.

In the construction of pins from high grade or expensive material, such as solid gold, silver, heavy rolled plate stock or the like, the body portion may be made very light or thin and still, owing to its cupped shape be sullieiently strong and durable for all practical purposes. When a cult-pin is constructed of such thin stock it has heretofore been found necessary to form the joint ears and catch member scjiarately and of heavier stock and to solder the same to the body, as when they were made all in one piece with the body portion, they were so thin and light that they were not practical being easily broken elf and the pin destroyed and in order to obtain this strength at the points desired the body portion would be much thicker than was necessary, thus unnecessarily increasing the cost of the pin.

In order to obviate the above diliieultics and yet form the joint integral with the body portion 1 have reduced the body por tion in thickness 'lormiug the same extremely thin and light and at the same time leaving that portion from which the joint is formed, of a thickness sullieient. to obtain the desired strength and stillness to withstand the necessary strains.

As illustrated in Figs. 3 and 1: an outwardly extending tongue -lis formed 011 one end of the body portion '1, the same being cut away or recessed at forming laterally extending portions (v having shoulders '7. A. slot 8 is also punched or otherwise formed through this tongue for the reception of the pin stem 9. Another tongue 10 extends outwardly from the opposite end of the pin body from which the catch member 3 is formed. The joint tongue is just enough thicker than the body portion to in sure the proper amount of strength which is required to serve as practical joint and catch members, the body portion having been reduced to the thinness requlred by rolling, sivaging, or otherwise. After having thus formed the blank the same is struck forming the body portion into a cupping form the tongue 6 being bent inward or toward the opposite end of the pin body and back upon itself as shown at 11 in Fig. 5, the

end 12 of this tongue resting adjacent and member against the bottom of the pin body a strongand rigid support is obtained to prevent movement when the pin stem en ges and rests upon its fulcrum point at 16 for the purpose or obtaining a tension vvhenf its pointed end engages the catch member 3.

The broad side face of this end portion extends into the hollow body portion and is arranged to lie adjacent to and parallel With the inner face of the end Wall of the pin body, which is a very neat, practical and effective way of disposing of and securing;

the free end of this joint member.

In order to more firmly secure this tongue end 12 the edges 1'? of the pin body may be rolled over the laterally extending shoulders 7 of this tongue thereby firmly and rigidly locking the same in position in the pin body Without the use of solder.

During the construction of my improved pin the head of the pin stem is inserted into position before the end 12 of the joint member is secured in position Within the body of the pin.

My improved construction of joint may be used on pins of any shape, but the same has its greatest advantage when used on pins substantially rectangular in shape and having practically square ends.

I claim:

1; A pin of the character described comprising a cupped body portionhaving an integral joint member formed at one end, said joint member being bent over and back toward the opposite end of the body to form a loop to receive the head of a pin stem, the Wall of said loop being provided With an. opening through which the shank of the pin stem may extend, the free end of said joint meml er extending down into the cupped portion of said body, the face of the bent over portion lying against the inner face of the end Wall of the cupped portion of said body. 7

2. A pin of the character described com prising a cupped body portion having an integral joint member formed at one end, and provided with shoulders, said joint member being bent over and back toward the opposite end of the body to form a loop 6 to receive the head of a pin stem, the Wall of said loop being provided with an open ing through Which the shank of the pin stem may extend, the free end of said joint member extending down into the cupped portion of said body, the face of the bent over portion lying against the inner face of the end Wall of the cupped portion of said body, the edges of the side Walls of said body being bent over said shoulders.

in testimony whereof I atliX my signature in presence of tWo Witnesses.
